The spirits say
As far as we can tell ( from Beta rumors ) SGG are testing 5* hero costumes in Hero Academy so they can give Gravemaker his costume.
In the Beta were SGG limited it solely to Tavern of Legends v2.0, there was a large amount of negative feedback.
At least this way marketing can honestly say, Gravemaker from Taverns, or free from Hero Academy, can also grant a lucky player Gravemaker’s costume
From what I can tell, SGG really wants to make Gravemaker, with matching costume, featured HotM for multiple Tavern appearances
